Is there a plugin for macros in IDCS5?

In the "good old days" of phototypesetting, we had the ability to store up to 10 copy/paste items, including formatting, into the F keys on the keyboard, so that they could be accessed with one keystroke. Is anything similar available for IDCS5? I already use styles and shortcuts, but formatting can still be tedious when a long document contains many repetitive elements.
